Researchers from King Fahd University of Petroleum and Minerals Report on Findings in Oxides (Electrochemical Reduction of Carbon Dioxide over CNT-Supported Nanoscale Copper Electrocatalysts)

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Oxides have been published. According to news reporting from Dhahran, Saudi Arabia, by NewsRx journalists, research stated, "This paper presents the experimental investigation of copper loaded carbon nanotubes (CNTs) electrocatalysts for the electrochemical reduction of carbon dioxide. The electrocatalysts were synthesized by homogeneous deposition precipitation method (HDP) using urea as precipitating agent."

The news correspondents obtained a quote from the research from the King Fahd University of Petroleum and Minerals, "The prepared catalysts were characterized by TEM, SEM, XRD, XPS, BET, and FTIR for their morphology and structure. Characterization results confirm the deposition of Cu nanoparticles (3-60 nm) on CNTs. Linear sweep voltammetry (LSV) and chronoamperometry (CA) were used to investigate the activity of the as-prepared catalysts for the electrochemical reduction of carbon dioxide. The electrocatalysts reduced CO2 with high current density in the potential range 0 similar to-3V versus SCE (standard calomel electrode). Among all catalysts tested, 20 wt. % copper loaded CNTs showed maximum activity. Gas chromatograph with TCD was used to analyze liquid phase composition."

According to the news reporters, the research concluded: "The faradaic efficiency for methanol formation was estimated to be 38.5%."
